    摘要: The present invention relates to magnetic beads suitable for, for example, isolation of proteins, cells, and viruses and also for diagnostic applications and cell cultivation. The magnetic beads are composite beads with an inner core of metal particles, which are coated with an inert synthetic polymer and these are then enclosed in a hydrophilic porous polymer, preferably agarose. This provides porous biocompatible beads without metal leakage. The beads may be used for cell cultivation or for chromatography. When the beads are used for chromatography the agarose layer is preferably provided with ligands having affinity for selected biomolecules.

    摘要: The present invention relates to a method for sample application and separation. More closely, the invention relates to convenient direct loading of a biomolecule sample via magnetic beads to, for example, a gel before electrophoresis. In this way, the invention combines elution and application steps with minimal losses of sample. Thus, the invention relates to a method for sample application of biomolecules on a separation media, comprising the following steps: a) obtaining said biomolecules from a sample by magnetic beads; b) applying the magnetic beads with the biomolecules to a separation medium; c) releasing the biomolecules into the separation media, and d) separation of the biomolecules from each other in the separation medium.
